Smarthome - Which system for new construction?

A useful combination is the season, presence of the residents, sun position, and indoor temperature. That way you can either provide shading or use the sunlight for heating. But that is hardly possible anymore with the internal logic functions of the actuators. Much more nice things can also be done with the shading.

It should work with the actuator. It has the ability to control the shading depending on the outside and inside temperature to maximize solar gains.
I haven't set it up myself yet.
I want to do it based on outside temperature, I consider inside temperature pointless in connection with a slow system like underfloor heating in a new building.

No logic engine or similar is required for this. Both are standard features of the MDT application. We also had both briefly activated, but it doesn't necessarily make sense for us. The outside temperature doesn't say anything about the solar radiation. At -5°C the sun can still overheat your place...
